About QOI

Quite OK Image Format

A lossless image format published by Dominic Szablewski in 2021, designed to encode and decode much faster than PNG at similar file sizes. Its whole specification fits on one page. Use it in games and tools that load many images and care more about decode speed than support in other apps.

About JXL

JPEG XL

An image format standardized as ISO/IEC 18181 in 2022, with lossy and lossless modes, HDR and alpha. It can repack an existing JPG losslessly into a file about 20 percent smaller. Use it for archiving photos or for apps that support it; browser support is limited, so check before using it on the web.
